Quick Answer
The answer is the Multiple Choice (Checkbox) variable type. This is the correct choice because it is the only ServiceNow catalog variable type designed specifically for multi-select behavior, allowing users to pick several options from a predefined list. Unlike the Single Choice (Radio Button) or Select Box types, which enforce a single selection, the Multiple Choice (Checkbox) type stores each selected value as a separate entry in the variable’s value field, making it ideal for scenarios like selecting multiple software licenses or departments. On the ServiceNow Certified Application Developer CAD exam, this question tests your understanding of catalog variable types and their use cases, often appearing in scenarios where a developer must match a requirement to the correct variable type. A common trap is confusing the Multiple Choice (Checkbox) with the Single Choice (Radio Button) or Select Box, so remember: checkboxes mean “check all that apply,” while radio buttons mean “pick one.” A helpful memory tip is to think of a checkbox list as a “multi-pick buffet” where you can grab several items, whereas radio buttons are a “single-choice vending machine.”
This SNOW-CAD practice question tests your understanding of core application development. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A developer needs to create a service catalog variable that allows the user to select multiple values from a predefined list. Which variable type should be used?
Single Line Text
Why wrong: Single Line Text is for single text input.
Radio Button
Why wrong: Radio Button allows only one selection.
Select Box
Why wrong: Select Box allows only one selection.
Multiple Choice (Checkbox)
Multiple Choice allows multiple selections.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Multiple Choice (Checkbox)
Option D is correct because the Multiple Choice (Checkbox) variable type in ServiceNow allows users to select multiple values from a predefined list. This is the only variable type that supports multi-select behavior, which is required when a user needs to choose more than one option from a set of choices.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Single Line Text
Why it's wrong here
Single Line Text is for single text input.
Radio Button
Why it's wrong here
Radio Button allows only one selection.
Select Box
Why it's wrong here
Select Box allows only one selection.
Multiple Choice (Checkbox)
Why this is correct
Multiple Choice allows multiple selections.

Common exam traps
ServiceNow often tests the distinction between single-select and multi-select variable types, and the trap here is that candidates confuse Select Box with Multiple Choice because both present a predefined list, but only Multiple Choice supports multiple selections.
Detailed technical explanation
In ServiceNow, the Multiple Choice (Checkbox) variable type stores the selected values as a comma-separated list in the database. When used in a catalog item or record producer, the variable's values can be referenced in scripts or workflows using dot-walking (e.g., `variable_name`) and can be iterated over using `gs.getProperty()` or `getValues()` methods. A real-world scenario is a hardware request form where users can select multiple accessories (e.g., mouse, keyboard, monitor) to be ordered together.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the SNOW-CAD exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
